You're not wrong, but sometimes you have to be pragmatic. I've done a lot of work building interfaces to acquire clinical data from healthcare provider organizations for care quality improvement. There are clear industry standards from HL7 (V2 Messaging, CDA, FHIR) but many provider organizations don't implement them correctly, so we had to accept a lot of junk and just find a way to deal with it. Many of those provider organizations lack IT resources and are at the mercy of their vendors or consultants, so trying to hold them to strict standards results in an impasse.
